So I was going to take monorail red for a spin after catching a movie at the AMC in Downtown Disney this evening, but when I was at the top of the steps, a cast member used the PA to tell us that the platform and vehicle itself needed to be evacuated. She calmly and clearly told us that we needed to exit the area as quickly as possible. I ended up just heading home after this, but I was curious if anyone had any idea what had happened. I did see one or two security cast members headed in that direction as I left. Anyone know what happened? I hope everything's all right.
